v0.54

[andy5995]

• Windows: keep your settings and mail under %APPDATA%\ncmail. Windows sets no
  HOME, so the reader used the directory it was started from -- for the Start
  Menu shortcut that is the install folder, which is not writable, and the
  settings file could not be saved ("Error writing config file"). (Windows 64 issue refuses to load #38)
• Windows: a settings file next to the program takes precedence over
  %APPDATA%\ncmail, so a portable copy keeps working, and so does an older
  installation that has always kept ncmail.rc beside ncmail.exe.
• Quote names taken from a packet before passing them to the archiver. A packet
  could name itself in a way that ran a command.
• Limit the length of the text fields read from an OPX packet header. A crafted
  packet could overflow a buffer.
• Read the door name and version from a QWK DOOR.ID without assuming the lines
  are well formed. A long or malformed line could overflow a buffer or crash.
• Update .ncmailrc and the colors file in place: your own comments and the order
  of the lines are kept, and the file is only touched when its keywords differ
  from the program's, so a new version alone no longer rewrites it and prompts
  you. (Update .ncmailrc in place instead of rewriting it #34)
• Draw text as Unicode on macOS and the BSDs too, where the wide curses calls
  were being compiled out. The build now asks curses for them, and the macOS
  build uses a Homebrew ncurses if one is installed.
• New "--version" and "--help" options. --version also reports the curses
  library, and whether the build and your terminal can show Unicode characters,
  which is worth including in a bug report.
• Draw ANSI art with the real block and line characters on a UTF-8 terminal,
  instead of the substitutes used when a terminal has no such characters. The
  character set setting no longer changes how the art looks there.
• Hold ANSI art to 80 columns and centre it. On a wider terminal each row used
  to run on into the next one, which sheared the picture.
• Fix a crash when the terminal was resized while the ANSI animator was
  running. The animator ignored the resize instead of passing it on.
• Remove the animation feature from the ANSI viewer. A program written for
  viewing animated ANSI does the job better.
• Release a macOS build for Apple Silicon: a tarball holding the program, the
  man page and the example color schemes. See README-macos.txt inside it.
• A Homebrew formula, in packaging/homebrew, for installing on macOS.
• The AppImage now bundles its own C library and terminfo database, so it runs
  on any Linux distribution, including musl-based and very old ones.
• The DOS download is now a zip file with a short name, like ncm054.zip. It
  holds NCMAIL.EXE and the documentation as text files. Every name inside fits
  the 8.3 rule, so you can copy it to a DOS computer and use it as it is. The
  old download had a long name that DOS could not keep.
• The Windows installer is about 1 MB smaller.
• New icon. The old one still showed the MultiMail name.
• Keep long names and addresses inside the window when showing a letter header
  or the address book, and when writing a header to a file.
• The "Charset:" popup shown by "C" now disappears on the next keypress.
  It used to stay on the screen and be partly overwritten as you moved
  through the list.
• Show the last line of the ANSI viewer's help screen. "Q - Quit ANSI viewer"
  was cut off.
• Draw the shadow under a popup correctly when the text behind it is not ASCII.
• Free the prompt window that "T" (take tagline) opens in the letter window.
  Each use leaked about 6 KB.
• The "Version" line in .ncmailrc and the colors file is no longer written or
  read. Nothing used it once the check above stopped depending on it. An
  existing line is ignored, and commented out if the file is ever updated.
